摘要： A synchronous switch valve core with a voltage stabilizing function, comprising: a valve core housing (1), a valve core base (2), a flow regulating module, and a balancing hydraulic module. The flow regulating module is capable of cutting off a cold/hot water path before water enters a pressure balancing module, thus preventing high-temperature water from immersing the valve core, preventing the building of lime scale, protecting the valve core, and extending the service life; moreover, water flow can enter the pressure balancing module only after flowing through the flow regulating module, thus preventing the channeling of hot and cold, and obviating the need to install a check valve at a water intake elbow. By means of an optimized design with respect to the parts of the synchronous switch valve core, the synchronous valve core is transformed from a switch capable only of regulating flow into a switch not only capable of regulating flow but also capable of synchronized switching, and also capable of balancing the pressures within two channels, thus transforming a product equipped with the vale core from a complex channel into a simple channel, and obviating the need for separately providing a balancing module part; a valve body is structurally simple, has a shortened water path, and is inexpensive.

摘要： An explosion protection valve for decoupling system parts or workpieces for the installation in a pipeline, comprising

a housing,
a closing body which is axially guided inside the housing on a guide rod and can be shifted from a defined open position into a sealing closed position in the event of a pressure or suction wave in the pipeline in at least one closing movement direction,
a spring assembly, which is in operative connection to the closing body, on the guide rod for holding the closing body in the open position,
a sealing ring on the inner side of the housing, against which the closing body can be pressed in its closed position, and
a receiving pocket, which is applied to the inner side of the housing and is preferably open counter to the closing movement direction (SB) of the closing body, for holding the sealing ring.

摘要： An apparatus for directing fluid flow is disclosed, including a valve structure having a chamber, a main port, a first port, and a second port, each of the ports being connected to the chamber. A poppet structure in the chamber is moveable between a first position blocking the first port and a second position blocking the second port. A first compliant member connecting the poppet structure to an inner wall of the chamber, is configured to alternate application of forces to the poppet structure, in opposite directions, between the first and second positions.

摘要： A valve unit is moveably accommodated in a valve housing having a valve seat. A coil spring is provided at an outer periphery of the valve unit to bias the valve unit in an axial direction of absorbing a backlash between a driving-side screw portion of a driving portion and a valve-side screw portion of the valve unit. Pressure losses of fluid at respective portions are so made to satisfy a relationship of “P0≥P1≥P2”, wherein “P0” is a pressure loss of the fluid passing through an outlet port, “P1” is a pressure loss of the fluid passing through an axial space formed between the valve unit and the valve seat in a condition that the valve unit is most separated from the valve seat, and “P2” is a pressure loss of the fluid passing through an axial gap formed between neighboring spring wire portions or passing through an axial gap formed between the coil spring and the valve seat.

摘要： A main stage in-line pressure control cartridge. The cartridge selectively controls flow in-line in the same direction as opposed to directing flow at a 90 degree angle like other cartridges. A tubular poppet can be mounted into a body and has a sliding control sleeve that can expose radial holes in the poppet to an open position and to seal the radial holes in a closed position. The cartridge can be configured in numerous ways in order to serve many functions, such as a pressure relief valve, a counterbalance valve, and a flow control valve. The cartridge can also be configured to allow or prevent reverse flow.

摘要： A device is disclosed that may include a spool valve having a first connector and a second connector and a spool movable for controlling flow between the first connector and the second connector, regardless of direction of flow through the spool valve. A pilot valve having an inlet and an outlet develops a command pressure. A feedback circuit having an inlet and an outlet develops a feedback pressure. The spool valve may be responsive to the command pressure and the feedback pressure. A fluid rectifier circuit is provided to connect the higher pressure of the first connector and second connector to the pilot valve inlet and feedback circuit inlet, and connect the other of the first connector and second connector to the pilot valve outlet and feedback circuit outlet.
